GEORGE EDWVARD LUDDEN, OF EAST BRAINTREE, MASSACHUSETTS.

SAIL-FASTENING DEVICE.

SPECIFICATION forming part of Letters Patent No. 340,588, dated April 2'7, I886.

Application filed February 25, 1886. Serial No. 193,262.

To all whom it may concern:

Be it known that I, GEORGE EDWARD LUD- DEN, a citizen of the United States, residing at East Braintree, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Sail-Fastening Devicrs; and I do hereby declare that the same are fully described in the following specificatiou and illustrated in the accompanying drawings.

This invention relates to improvements in devices for securing sails on vessels to the mast hoops or rings, and it is carried out as follows, reference being bad to the accompanying drawings, where- Figure 1 represents a plan view of the sailfastening device. Fig. 2 represents a side elevation of the same. Fig. 3 represents a perspective view of it shown open ready for coupling the sail to it, and Fig. 4 represents a cross section on the line A B. (Shown in Fig. 2.)

Similar letters refer to similar parts whereever they occur on the different parts of the drawings.

Heretofore sails have generally been secured to the mast hoops or rings by means of twine, marling, or similar cords wound through the grummet-holes in the sail and around a portion of the mast hoop or ring; but this is objectionable, as it requires considerable time to attach and detach asail to its mast-hoops. I use no cords whatever, the device being made entirely of metal, as follows:

In the drawings, or represents a portion of a sail. b represents one of the grummets or perforations near its edge, as usual; and 0 represents one of the mast hoops or rings surrounding the mast on a vessel in the ordinary manner.

The improved fastening device is composed of the 3 shaped shield or plate d, placed from the inside of the mast-hoop c, and embracing the latter, as shown. By means of screw-bolts e and e is secured to the upper and lower rear ends of said shield or plate at the back plate, F, between which and plate at the masthoop c is clamped, and, if so desired, the latter may be still further secured by means of (No model.)

a screw, passing through a hole in plate F and screwed into the mast-hoop c, as shown in Fig. 4; but such screw may be dispensed with, if so desired. .To the screw-bolt e is hinged one end of the bow h, that is similar in shape to the bow ofa padlock. The other end of said bow is adapted to be secured to ears or projectionsff on one side of the rear portion of plate F by means of the thumb-screw t, that passes loosely through the upper ear, f, and the free bow end h, and is screwed into the lower ear or projection, f, as shown.

The curved plate d and back plate, F, may be secured in place on the mast-hoop either before or after the latter is slipped over the mast. If it is desired to secure the sail to the hoop, all that is needed is to unscrew the thumb-screw i and swing the bow h backward, as shown in Fig. 3, when the free end of the latter can easily be introduced into the grommet or hole near the edge of the sail, after which the bow is swung into the position shown in Figs. 1, 2, and 4, and locked in such position to the back-plate F, by means of the thumb-screw i, as shown.

By this very simple device a sail can readily be unshipped from the mast hoops and another put in its place without any unnecessary loss of time. Another advantage is that the sail is permitted to swing to the right and left of the mast with the utmost freedom, even if the hoops should happen to bind or stick on the mast.

Having thus fully described the nature, construction, and operation of my invention, I wish to secure by Letters Patent and claim- The herein-described sail-fastening device, consisting of the shield-plate d and back plate, F, secured together in a detachable manner by means of the screws 6 6, combined with the bow h,hinged to one end of plate F,and adapted to be secured to the other end of such plate by the set screw or thumb-screw i, as and for
